Question

A 350 gal air storage tank is initially at 100 psig. For how long can the tank supply 30 cfm of air to a machine that requires at least 80 psig to operate?

Answer 1

93.8 sec

Step-by-step explanation:

it is given that tab has 350 gallon

we know that 1 gallon = 0.134 cubic foot

350 gallon = 350×0.134=46.9 cubic foot

the delivery pressure is 100 psi which is greater than 80 psi to operate machine

it is given that supply volume is 30 cubic foot per minute

=
`(30)/(60)=0.5`
`ft^(3)/sec`

`time\ required\ =(tab\ air )/(supply\ volume)`

`time\ required\=  [tex](46.9)/(0.5)`

=93.8 sec
